Robot cameos
I knew they looked familiar! . . . must be from one of Fleischer's episodes of Superman!. Which, if I'd thought of it, I would have included in the list of "looks kinda like" in my previous post.
There's another robot I recognized from an old Astounding or Amazing cover, but I didn't want to spend hours searching the Web. I'll bet you can find it, once you've seen it.
Take it from me, Tom: you're gonna love this movie. It was made for our particular species of geek.
